RESUMO
The fields of emergency medicine and resuscitation are indebted to the Baron Dominique-Jean Larrey (1766-1842) for significant advances in patient care. Larrey was a great surgeon who served in the French army during Napoleon's rule. He developed one of the first ambulance services, utilized positive pressure ventilation, and introduced hypothermia as a form of therapy. He dedicated his professional life to improving the care of wounded soldiers on the battlefield. Larrey coined the term "Triage" to allocate resources to those most in need of emergent care. Today, many of his techniques still prevail in modern medicine.

Luigi Galvani became one of the greatest scientists of the 18th century with his research and the development of his theory on animal electricity. His work was appreciated by many scientists. Nevertheless, it gave rise to one of the most passionate scientific debates in history when Alessandro Volta postulated that Galvani had confused intrinsic animal electricity with small currents produced by metals. This debate would result in the creation of electrophysiology, electromagnetism, electrochemistry and the electrical battery. Galvani responded to each of the postulated theories of Volta giving irrefutable proof of the involvement of electricity in the contraction of muscles. However, his work was subsequently abandoned and silenced for many years but his ideas and theories were finally confirmed by the creation of new instruments and the interest of new scientists who helped position Galvani as the father of electrophysiology.

Acute splenic sequestration crisis is a common, potentially life-threatening complication of sickle cell anemia in children that is uncommon in adults.We present the case of a 44-year-old gentleman with undiagnosed hemoglobin S-C disease who developed intense back pain, marked abdominal distension, systemic inflammatory response syndrome, and multisystem organ failure that first presented as acute splenic sequestration crisis. The hemoglobinopathy SC is a disease caused by heterozygous-globin chain mutations with over-lapping clinical features of sickle cell disease with changes in the frequency of these manifestations reflected by the combination of characteristics of hemoglobin C and hemoglobin S. In hemoglobin S-C disease, autosplenectomy is rare and splenomegaly usually persists until adulthood;vasoocclusive complications are seen less habitually and become evident at a later time compared with sickle cell disease. The diagnosis of hemoglobin S-C disease is essentially done by exclusion. Transfusion of red blood cells is the treatment of choice, but splenectomy is indicated if transfusion therapy fails. A review of the literature and keypoints for the emergency practitioner are included.
